QUESTION|TASK 1

Include the tables created from PY4DS: CH2 Data Visualization used to create the above chart (Hint: copy the code from 2.2.1. The penguins data frame and paste each in the cells below)

# Include and execute your code here
penguins = load_penguins()

QUESTION|TASK 2

Recreate the example charts from PY4DS: CH2 Data Visualization of the textbook. (Hint: copy the chart code from 2.2.3. Creating a plot, one plot for each cell below)

(
    ggplot(data=penguins, mapping=aes(x="flipper_length_mm", y="body_mass_g"))
    + geom_point(aes(color="species", shape="species"))
    + geom_smooth(method="lm")
    + labs(
        title="Body mass and flipper length",
        subtitle="Dimensions for Adelie, Chinstrap, and Gentoo Penguins",
        x="Flipper length (mm)",
        y="Body mass (g)",
        color="Species",
        shape="Species",
    )
)

This is a dot plot that is colored by species.

# Include and execute your code here
(
    ggplot(
        data=penguins,
        mapping=aes(x="flipper_length_mm", y="body_mass_g", color="species"),
    )
    + geom_point()
)

This plot adds a smooth curve displaying the relationship between body mass and flipper length.

# Include and execute your code here
(
    ggplot(
        data=penguins,
        mapping=aes(x="flipper_length_mm", y="body_mass_g", color="species"),
    )
    + geom_point()
    + geom_smooth(method="lm")
)

This makes sure it calculates for the entire date instead of calculating per species.

# Include and execute your code here
(
    ggplot(data=penguins, mapping=aes(x="flipper_length_mm", y="body_mass_g"))
    + geom_point(mapping=aes(color="species"))
    + geom_smooth(method="lm")
)

This also adds shape for species to be more human-readable.

# Include and execute your code here
(
    ggplot(data=penguins, mapping=aes(x="flipper_length_mm", y="body_mass_g"))
    + geom_point(mapping=aes(color="species", shape="species"))
    + geom_smooth(method="lm")
)
